Laboratory asset markets provide an experimental setting in which to observe investor behavior. Over more than a decade, numerous studies have found that participants in laboratory experiments frequently drive asset prices far above fundamental value, after which the prices crash. This...

A new set of methodologies extracts key nonlinearities in the dynamics of financial markets from data that would appear to be completely random with ordinary linear time series methods. The understanding acquired from this analysis forms a basis for modeling conflicting and competing motivations...

An experimental asset market is used to test the effect of news concerning the underlying value of an asset on its trading price. Participants were divided into two groups and received different expected earnings values. Statistical support is found for the hypothesis that investors underreact...

We study overreaction and the cumulative effect of the consecutive local overreaction patterns in financial markets. The 'overreaction diamond' pattern [1] is one of the key components of a financial market bubble. The cumulative effect of the consecutive short term overreactions arising from...

Numerical computations are performed on a model which has been proposed to describe the characteristic and psychological aspects of financial markets in a pure setting. Overreactions, fluctuations and convergence to realistic values are observed in these calculations. By varying parameters...
